Has this IR ended already? In four turns, every villain defeated, or close to it? This just isn't working out the way the others did I'm afraid...
And just one thing breaks the DBZ analogy--the villains have never even really been allowed to be an honest threat. When Frieza and Cell go at Gokku, there's always a moment where you say "Oh crap, he's screwed."
But there's never been a villain who could touch Forrester. Even the City of the Gods was outflanked.
I blame 10th level magic. If there was some limit to it, it'd work... but really, there's no reason to have 11th, when you're the only guys with 10th. If lower-level magic was allowed to counteract it somewhat--if it was good but not quite as good as 11th (highly accurate scryings, instead of perfect scryings for example...), well then this IR wouldn't have broken down the way it has. And it has broken, I'm afraid.
And also--being a remorseless bastard should have some effect. In Dark Sun, if you're an evil son of a--witch-- you practice defiling magic and you beat the good guys to the power, at least short-term. Making good and evil's research abilities the same--well, you lose the fact that power's got a price... and you either try to pay it responisbly and take your time, or you say "Screw you" to the world, and smash forward heedlessly...
Ehh, I'm rambling... I'm in this to the end, mind you (of course, that might have already come for me) but when a horde of demons is a PL 28--well, I start wondering what evil can do to even the gap?
